BALL-BEARING.

Application filed May 14, 1919.

To (aid w/w/a 2'6 may concern Be it known. that 1, linear R. RnYNoLns, acitizen of the United States of America, residing at New Britain,Connecticut, have invented a new and useful Ball-Bearing, of which thefollowing is a specification.

My inventionrelates to improven'ients in antifriction bearings of thedouble row ball type and is primarily an improvement upon the bearingset forth in Ca-rlsonPatent :tt 1,222,846 of April 17th, 1917. Theobject of the present invention is to improve the means and method bywhich the bearing is assembled with a view to increasing the la/strength, durability and eficiency of the same.

Til the accompanying drawings:

Figure lis a crossscction of the finished bearing.

Fig. 2 is a similar view as the parts appear in the process ofassembling.

Fig. 3 is a view of the edge of the bearing complete.

Fig. 4: is a side elevation of hearing.

The bearing is made up of outer and inner ring elements which are soformed as to provide two sets of race-ways in which are arranged twoseries of balls. One of the ring elements, preferably the outer one, ismade up of two axially displaceable ring sections, which sections, inthe finished hearing, are permanently an endless integral ring.

In the drawings T have shown only the preferred embodiment of myinvention.

1 represents an inner bearing ring element which in this so shaped as toprovide two inwardly facing bearing shoulders or ball tracks 2-3. Theouter bearing ring element is made in two sections t and 5, each ofwhich is provided with an outwardly facing; bearingshoulder or balltrack. These tracks are indicated respectively 78. 9-9 are the halls ofone series, while 10 10 are the balls of a second series. The halls 99are arranged between the complementary tracks 27 While the balls 10 arearranged between the complementary tracks 3-8. The width of the ringmembers 4-.5 is such that when they are brought together as shown inFig. 2, the balls 9-9' may be successively introduced, the balls til-10having been previously introduced by simply displacing the inner ringthe complete specification of Letters Itatent.

l relatively to the member to a suliicient extent to permit all of theballs to be freely inserted. When this first series of balls lO-l0 isintroduced, the bearing rings are moved into the position shown in Fig.2, and the balls 9-9 are then inserted. To facilitate this operation, aside entrance notch 6 may be provided at one point in the ring section4-. ll--l2 are hall spacing; members which may be provided, the samebeing formed in any suitable way to space the balls shown. Theparticular form of the ball spacing device may be modified in a varietyof ways. letare annular recesses in the outer surfaces of the ring'sections '-l-5 respectively, the same being provided to receive a ring;spacing means which will now bedescribed.

When the race-ways have both been filled with the desired complement ofballs, the two bearing ring members 4.5 are moved apart as indicated inFig. 1. An endless band or ring 18 is then slipped over the bearinguntil it stands over the annular recesses l4r-l5. Powerful pressure isthen applied to the band 16 to reduce it circumferentially and tothereby force it bodily into the said recesses so that it will act as apermanent spacer for the ring; sections l-5, as shown in Fig. 1. Thiscircumferential reduction of the band 16 results in causing the crosssection thereof to be somewhat increased, so that as it is crowded intoits seat, between the ring sections 4c-5, it will cause said sections tobe pressed apart so that the balls 9--10 will be snugly seated in theirrespective raee-ways.

At any suitable intervals in the circumfen ence of the ring; members 4:and 5, notches may be provided adjacent to the space to be. occupied bythe spacer band 16 so that a portion of the metal of said band may flowinto said notches to form interlockin keys as indicated at l7-17 in Fig.3 wherehy the rin sections d-5 may not turn independent y. ien finishedthe outer ring element is practically a unitary structure.

' Any suitable means may be provided for forcing the endless band 16into position between the parts 45 so long as said means is powerfulenough to actually reduce the I endless ring cir cum'ferentially andcausethc metal to properly fill said space and any notches providedtherein to receive the "aforesaid interlocking .keys.

When the bearing is fully assembled, any irregularity that may possiblybe present on the outer surface where the spacer band 16 meets the outerring sections 45 may be round down to a proper finish.

ince the spacer band..16 is sub ected to no wear this part of thebearing may be unhardened, whereas the parts 1, 4 and 5 are of coursehardened. The band 16 is prefer 7 made of iron or. steel or any materialbl sufficiently hard to withstand heat and such pressure as would beoccasioned in 'the event the bearing is required to withstand thrust,and it shouldbe said in this connection that a bearing of this type iswell adapted to take endwise thrust by reason of the relativelv obliqueposition-mg of the complementary ball tracks. I a'maware that here-.tofore bearings of this general character have been produced in whichthe ring ele-- ments have been separated by soft metal,

heated and introduced in a' fused state, but

f obviously such metal is too soft to withstand for any lengtlrof timethe pressure of endwise thnust. Furthermore, in the assembling of such abearing there is danger thatlthe molten material may flow into the spaceto be occupied by the balls to the injury thereof. In the case ofthe'Carlson construction which employs a hard metal strip of a lengthapproximating the circumference of the bearing, it is obvious that'muc-h difliculty'will beexperienced in making the strip of exactly theproper length to cause the ends thereof to come snugly tomember havingannular shoulders to provide thrust receiving ball tracks, a pair ofbearing member's concentrically arranged.

with respect to said channeled member and having annular ball tracksconfronting the ball tracks of said. channeled member, said bearingmembers being displaceable axially toward each other to permit balls tobe in troduced between confronting ball tracks, two sets ofballsrbetween said confronting sets of ball tracks and spreading meansfor 1 said bearing members comprising an endless hard metal spreadingmember permanently secured between the axially displaceable bearingmembers to hold the same spaced apart to maintain the respective balltracks thereon in proper operative relation with the confronting balltracks on the other 1 bearing member, said parts bein constructed to.enable the insertion and of said spreading member between said am- .allydisplaceable bearing members inthe act of assembling the bearing.

2. A ball bearing comprising a bearing member provided with two spacedball races, at cooperating bearing member composed of a plurality ofaxially displaceable rings each constructed to provlde a ball race tocooperate with one of the ball races on the first mentioned bearingmember, two rows of balls in the spaces between cooperating ball races,a non-removable hard metal endless band between said two rings operatingto hold the same at fixed operative relation to cause the'companion ballraces to properly engage said two rows of balls and means permanentlysecuring said hard metal spacing member in spacing position between thetwo rings of the two-part bearing member.

3. In a ball bearing of the double row type, twoannular bearing membershaving two sets of ball races to receive two rows of balls, oneof saidbearing members comprising two' rings axially displaceable to permit of.the assembling of the bearing when said rings are brought together, ahard metal deformable spacing device in the form of an endless band, thetwo ring bearing member having a recess to receive said spacing memher,the bottom of said recess forming a supporting-platform for saiddeformable spacing member. v

4. In a bearing of the character described, a one-piece bearing ringmember having two oppositely faced ball tracks, a two-piece bearing ringmember having complemeneformation .oppositely faced ball tracks, atwo-piecc bearing ring member having complementary ball tracks for thefirst mentioned ball tracks respectively, the two pieces of said secondbearing member being axially displaceable, and an endless band of hardmetal located between the two pieces of the second hearing member topermanently hold the same in operative position, notches in the twoparts of said two-part member adjacent to said endless band withportions of said endless band extending into said notches to forminterlocking keys to prevent the hide pendent rotation of said twoparts.

6. The herein disclosed process of securing the two race rings of a ballbearing in permanently spaced relation which comprises defonning anendless spacing hand of different diameter from said race rii'igs into aspace between the rings to thereby provide a continuous spacing elementholding the rings in separated relation.

7. The herein disclosed process of securing the race rings of a ballbearing in pen manently spaced relation which comprises compressing anendless spacing band of greater diameter than said race rings intoaspace between the rings to thereby provide. a continuous spacer holdingthe rings in separated relation.
